We do notify on the ::pressed property after touch begin/end and
recording the event sequence, but we do not return the correct value
if the button was triggered via touch.
Consider the event sequence also in the ::pressed getter, so the
button is considered pressed.

Since commit f60a469a34, everything outside the fade area is painted
fully transparent. That is required for the fade effect during app
grid navigation, to prevent unfaded parts of surrounding pages
becoming visible on wide-screen displays.
However in most other cases, that behavior is the exact opposite
of what we want: Elements outside the fade area (like scroll bars)
should never fade.
In order to fix the regular case, hide the new behavior behind a
property.

With commits fab39bbea5 and
62e40a1350 we started depending on a new
ClutterActor API: clutter_actor_invalidate_paint_volume()
Given that this commit was applied to the 40 stable release, it broke
ABI compatibility with mutter, which is something we guarantee between
stable releases. So use GModule to dynamically find the symbol in our
loaded libraries. If it exists, use it and invalidate the paint volume.
If it doesn't exist, libmutter is still at version 40.0 and we don't
need to invalidate the paint volume.
This also adds a dependency on gmodule. We need to link against gmodule
to use g_module_open() and g_module_symbol() APIs.

StWidget is overriding ClutterActors get_paint_volume() vfunc to adjust
for overpaint of things like box shadows that get set in CSS, it does
that by setting the paint volume to the theme nodes paint box.
Since StWidget can't really get notified when the paint box changes, we
just invalidate the paint volume when the theme nodes paint_equal()
returns FALSE.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1484>
Since StViewport uses the value of the StAdjustment to create its custom
paint volume, ClutterActors newly introduced proper caching of paint
volumes doesn't get notifed about changes to that paint volume and will
simply reuse the cached old one.
So make use of the newly introduced
clutter_actor_invalidate_paint_volume() method to make sure ClutterActor
will ask for the paint volume again on the next paint.

Creating a content object from a cairo surface may fail, in which case
we return an empty content with a 0x0 preferred size.
However when we treat such a content object as GIcon, we happily load
it anyway. Don't do that, so consumers like StIcon can fall back properly
to an alternative.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1761>
While most GIcons passed to this function cause a StImageContent to be
created with the requested size, cairo surface based icons already are
passed as StImageContent with a preferred size corresponding to the
size of the surface they were created from. As a result icons of window
backed applications were never scaled up like the other icons. Fix this
by ignoring the content size for these case.

This is how the code works and how it is already used from the C side.
There would also be no point in keeping this transfer none, because
textures generated from this function will not be shared and are not
kept in the cache.

This reverts commit 87558efbf1.
The commit did not fix the bug it was supposed to fix, it just
complicated the code. The hopefully correct fix is in the previous
commit.
The point of this commit was to ensure everything gets removed when
bind->source gets removed. This however was already the case since the
signal handler was already connected to bind->source and has a
destructor registered that takes care of everything. And since gobject
destroys its signal handlers before it clears the weak refs, this new
weak ref was effectively never being used.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1718>
If the icon surface of a window got updated and its type or format no
longer match what we expect, st_texture_cache_reset_texture() might
overwrite the existing image in the bind with a new image, while still
keeping the weak ref on the old image. Due to this the old image might
trigger a st_texture_cache_on_pixbuf_notify() after the bind has already
been freed by g_signal_handlers_destroy() in the bind source. While this
usually would remove the weak ref, the weak ref it tries to remove is
on the new image, not the old one. The call to
st_texture_cache_on_pixbuf_notify() then tries to read the already
free'd memory from the bind which causes the cast to G_OBJECT to fail,
resulting in the crash.

This will be needed for fine tuning of the visible area for appGrid
navigation purposes. We most nominally can let it happen via CSS as
the size calculations happen on size allocate, so we want to avoid
triggering relayouts while adapting to the given size.

Instead of taking just vertical/horizontal offsets, take a ClutterMargin
to allow us set the fade offsets on each direction specifically. Also,
handle negative values in margins, the fade effect will run in the negative
space left by the scrollview padding instead. Another difference now is
that areas outside the extents of the effect will be transparent, instead
of the effect ending abruptly past the given extents.
This will be used by the app grid, in order to selectively let see either
of next/prev pages while navigating.
While at it, fix code style issues in st_scroll_view_update_fade_effect(),
and clean up unused variables from the GLSL code.

This property controls whether the viewport clips the content to its own
allocation or not. This will be necessary in special modes that we want to

Commit 473e77e2c5 fixed applying the :insensitive pseudo class to
initially unreactive widgets, and adjusted the style test to work
with that.
In hindsight, we can do better than just making the test work, and
include a test case for the :insensitive styling as well (namely
the issue the previous commit was fixing).
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1649>
We are applying the :insensitive pseudo class to unreactive widgets,
or at least we are supposed to. As we currently only update the style
on notify, we don't apply it to initially unreactive widgets.
This was covered up partially until recently when Clutter started to
use G_PARAM_EXPLICIT_NOTIFY. Before that, the notify handler would run
when explicitly setting :reactive to FALSE at construction time.
Make sure we always apply the pseudo class correctly by updating it
after construct properties have been set.

We want to use the fast path of filling the entire area if either the
left and right shadows would overlap or the top and bottom shadows. The
latter check was wrong due to a typo resulting in the regular path
being used in some cases it couldn't (and shouldn't) handle.
This was causing the inset shadow used to highlight panel buttons to
not appear for buttons above a certain width.

The shader code currently only accounts for padding for the
bottom and right fades, but not for top and left.
As a result, we only fade the right edge when swiping through app
picker pages, whoops.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1569>
What the blur shader does is going n_steps in each direction (e.g. in case
we're in the horizontal pass that means left and right direction), sampling
the adjacent texels of the texel we're currently blurring. That means
n_steps actually is the amount of texels we're sampling in one direction,
not in both directions.
Make n_steps match what the blur shader does, and rename it to sampling_radius
to match what it really means. Do that for both st-theme-node-drawing.c and
st-private.c

In some styles the top or left sections of box-shadows would go missing
even though they had non-zero thickness. This was because the inner
local coordinates could become very slightly negative and were then
incorrectly judged to be invisible.
Negative coordinates should not be ignored because that's where the
entire top/left sections of shadow are meant to exist. It's only the
sections of shadow with zero thickness that we should skip.

Not checking for this would result in `clutter_actor_add_child`
failing, but StBin keeping a copy in `priv->child`. So later on,
`st_bin_remove` would never be called on it and this assertion
would fail and crash the whole shell:
```
static void
st_bin_destroy (ClutterActor *actor)
{
StBinPrivate *priv = st_bin_get_instance_private (ST_BIN (actor));
if (priv->child)
clutter_actor_destroy (priv->child);
g_assert (priv->child == NULL);
```
By disallowing spurious `st_bin_set_child` calls we now prevent StBin
from entering such a corrupt state and the above assertion won't fail
anymore.

Just like the internal ClutterText, the icon actors are part of the
entry. It therefore makes sense for the icons to not react to clicks
when the entry itself is non-reactive; again, just like the text.
That behavior is also consistent with icons in GTK entries.

Like `GtkAdjustment`, `StAdjustment:changed` is not emitted for the
`value` property except when changed with `st_adjustment_set_values()`.

However GError** arguments appear as throws="1" in the GIR anyway

Much of St is undocumented, aside from input/output arguments. This is
no doubt because a lot of it parallels Gtk closely, but is worth
improving since many new programmers are not familiar with Gtk.
